Abstract: | The complex Mn(apo)6Cl2 (apo=2-aminopyridine N-oxide) was obtained by the that the complex is mononuclear with octahedral coordination environment (MnC30H36N12O6Cl2). The oxygen atoms from apo ligands coordinate to the manganese atom forming Mn(apo)6C12. The compound Mn(apo)6Cl2 is hexagonally symmetric with space group R3,lattice constants: a = 12.010(2), b = 12.010(2), c = 20.232(4) A, γ= 120°, V= 2527.4(7) A3, Z=3,Mr =786.55, Dc=1.550 g/cm3, μ= 0.6141mm-1, F(000) = 1221, R = 0.0541, Rw = 0.0580 for 1229 reflections with Ⅰ>2σ(Ⅰ). The distances between Mn(Ⅱ) and O atoms are in the range from 2.171(5) to 2.184(5) A, and the distance between the chlorine anion and N atom of amido group is 3.3 A. The dihedral angle between two adjacent pyridine ring planes is 59.19 (0.17)°. |
